A New Approach in Cloud Environment to Improve Data Security Using Multiple Bits

Cloud computing is one of the prominent dynamic term, which provide different services for the user and also prevent the user from burdens of local storage issues. Security is one of the biggest issues and offers new challenges to researchers for protecting the data from unreliable services to provide the solution for this issues number of ways. This paper concentrates on the security with the help of steganography before storing into the cloud environment. In this proposed method, the data is hidden into the image and that image is stored into the cloud space. For this use, LSB steganography has been proposed by considering LSB and MSB pixels for hiding and retrieval of the data which is an improvised version of one bit LSB technique. The effectiveness of the proposed method has been estimated by computing mean square error (MSE) and peak signal to noise ratio (PSNR).
